Number Four
Number Four, or John Smith (formerly known as "Daniel Jones"), is 16-years old (as of The Power of Six). He is the protagonist and narrator of the first novel, I Am Number Four, and half of The Power of Six and The Rise of Nine. John is Number Four in the sequence protecting the ten Lorien children living and hiding on Earth. He is described as being a fit, very attractive young man with dark blonde hair. He has three circular scars on his right ankle, symbolizing the three dead Lorien children, and a scar similar to the pendant all the Lorien children wear, signifying the charm that protects them. John falls in love with high school junior Sarah Hart in the first book. In The Power of Six he develops feelings for number Six as well, although these subside in the third book, and his feelings for Sarah take over. Four also has a friend named Sam Goode who travels with him and Six in a search for his father who he believes to be a prisoner of the Mogadoriens. His Cêpan was named Henri, who dies at the end of the first book. At the end of the second book, Four and Nine go North in an attempt to find Six. It is also revealed in the third book that he may be the Garde who inherits all of Pittacus Lore's powers, with Nine and Eight as the other two possibilities. His Legacies include:
Lumen - The ability to produce fire, heat, and light from the users hands, and a resistance to heat, fire, and burns. John's grandfather had this power.
Animal Telepathy - The ability to communicate with animals. He discovered this Legacy last, near the end of the book one despite it being his first Legacy, happening before the timeline of the book.
Precognition - Ability to see the future (John has shown this ability a couple of times, though it is unconfirmed whether or not this is one of his Legacies)
Telekinesis - Like all Garde, Four can move objects with his mind.
Enhancement - All Garde possess enhanced physical strength, speed, reflexes, endurance and durability.
Area Healing - He learns this while in the fight in The Rise of Nine, when Sarah and Ella are shot and dying, he concentrates on how badly he does not want Sarah or Ella to die and heals them.
In the film adaptation, Number Four is portrayed by Alex Pettyfer.
